Text-to-Speech for Arduino


requires an amplifier on the PWM output pin, e.g., <![CDATA[]]>this one<![CDATA[]]>
original implementation by Clive Webster in <![CDATA[]]>Webbotlib<![CDATA[]]>
ported to Arduino by <![CDATA[]]>Gabriel Petrut<![CDATA[]]>
Stephen Crane modified it to use pins other than pin 10 with the help of <![CDATA[]]>this tutorial<![CDATA[]]>
see <![CDATA[]]>blog articles<![CDATA[]]>
note that it works with <![CDATA[]]>ArduTouch<![CDATA[]]> by setting output on pin 9.




Text-to-Speech for ARM with DAC


add support for ARM processors with DAC
PWM filter not required with DAC, but still need audio amp and speaker. DACs can source only about 1 ma
tested on Teensy 3.1, 3.5, 3.6, LC, and DUE

also added AVR support for Leonardo pin 5 (timer 3)
